alt Hacker NewsPoW schemes like Anubis don't work. Increasingly bots are using headless browsers and are basically able to solve captchas, proof-of-work(s) and basically bypass all any any attempts to block them. It's becoming impossible to stop bots from hammering your sites/services for unwanted traffic.

There's one or a small number of actors who are DDoSing the internet right now, and those are the ones you care about. What's the purpose for blocking non-DDoS bots?

You are asserting that they don't work without explanation or evidence. Meanwhile it isn't clear why they wouldn't and indeed they appear to accomplish the stated goal of severely rate limiting scrapers.

The most recent captchas that involve basic reasoning can block majority of bots today.

Seems like there is no POW "solving" if the POW in question is literally solving some sort of mathematical puzzle. It has a bounds and we can just scale the bounds depending on how much abuse we are seeing.
I've never understood why that isn't more common honestly. It would be cool if I could actually transfer POW from one domain to another as well. Probably wouldn't stop scrapers, but it would likely stop low margin fraud type things.
